Replacement Rotors, recommendations?

Upon trying to change my front brake pads the other day, noticed my rotors are warped, going over them with my finger, they have a wavy feel, mechanic said cutting them won't help and that a replacement is needed. Says the back is absolutely fine

I have a 2013 Limited 2.0T, are rotors covered under warranty? If not, any recommendations on a replacement besides OEM, because they're expensive for no reason...

It's a wear item.

Buy them from your dealer or your local auto part store.

Rotors can be turned if in spec. Can't tell a rotor is bad by running finger over it, especially with all the common ceramic pads that don't wear rotors.

Have the rotors measured with a micrometer for thickness. Cutting them will help if in spec.

Rotors is an expendible wear item, just like the friction material on pads,, usually only a 1 yr warranty for material and workmanship.. You been using them for stopping for 3 yr with no concerns, so now it is a weather / wear concern with use over time.

Rotors, they all cast iron, hit local part store

When you replace rotors, make sure the face on the hub' flange is clean/free of rust and debris.. thus rotors will sit flat to flange with minimal run-out (swash)..

If you choose to cut rotors, on-car is best way to go..

I've tried LOTS of different brake parts, the usual stuff from CarQuest and AutoZone. Some are good, some....feh.

When I needed parts for the Accent I went to Rock Auto and got Centric Posi-Quiet, their mid-grade line. WOW! I could not believe the brake response and the resistance to fade. I though my tC stopped on a dime, after I put these in the Accent I wondered why the Scion's brakes were so bad. The next year I put them in the Scion.

If they don't change anything, I'll probably never use anything else again.

Do you know any satisfying profanity?!

thanks for the recommendation, just looked up the part number.

They don't differentiate between left or right? Safe to just buy 2 fronts, correct?

ahh, rotors. house brand vs others. of course, the house brand is always the least expensive. they also have the shortest warranty. like a year. and they are always made in china. guess which ones get warranted the most? sometimes you can tell the difference in quality just by looking at the part. this is one of them.

Usually rotors are rotos, so if they don't say Left and Right you're good to go. Pads come in kits of 4, two for each side.

More dependent on wheel size. Bigger wheels can accommodate a bigger rotor, so sometimes they up the circumference of the rotor especially if there is a horsepower increase between the models.

You can get rotors easily that have the no braking surfaces plated or otherwise treated so they don't rust.
